The invention is more particularly concerned with automobile curtains but itwill be obvious from the following specification that it may also be employed in various other In the constructions towhich constructions. the invention relates the curtains are provided with a convenient or desired number of posts and the framework about the openings to be closed with correspondingsockets to receive the posts which are provided with socket-engaging members to interlock therewith. It is desirable for obvious reasons that the socket members project as little as possible beyond the surface of the frame and otherwise be as unobtrusive as possible. The improved socket meets this requirementpresenting a neat inconspicuous appearance when the curtain is off, and .is then automatically closed against the entrance of matter which might clog'it and prevent the entrance of the post.

In the drawing accompanying and forming a part of this specification Figure 1 is a central section of a preferred embodiment of the invention artly in elevation; Fig. 2 is a side elevation thereof; Fig-3a face or plan View; Fig.4 a bottom plan; Fig. 5 a face plan of the main socket member or cup; Fig 6 a section on the line 66 of Fig. 5'; and Fig. 7 a section of another element of the device.

It has not been thought necessary to show the post member of fastener, a variety of such suit-able for use with the'improved socket being known inv the patented art and "on the market.

The socket comprises a cup member 8. an attaching screw 9, an annular catch or flange member 10, a closure plate 1.1 and a spring 12. The cup member is struck up out of sheet metal of suitable strength intothe shape shown in Figs. 5 and 6 and comprising a cylindrical barrel 13 with an outwardly turned octagonal flange 14 at one end thereof, the other end of the cup being somewhat reduced and of hexa gonal or other angular cross section as at 15. The bottom of the cup is centrally perforated at 16 for the reception of the shank of the screw 9. The head of the screw is hexagonal or of other shape to fit the reduced bottom portion of the cup. In assembling the socket the screw is dropped into place and the cup pinched in over the head thereof to provide a number of abutwe e 17' W sh P v nt axial movement of the screw'toward the open end of'the cup, as shown byFig. 1.v

The flange or catchmember 10 is struck up in theform shown in Fig. 7 with the inwardly sloping funnel-shapedyportion 18 terminating in stiffening flange 19 and the outer octagonal flange 20. I v

In assembling the socket, after the screw has been secured in position,'the spring 12 is inserted, the closure plate 11 put in position with the flange 21 inturned, then the annular catch member is placed over flange 14 and flange 20 turned under the latter. The socket is then complete, ready for use.

In applying the sockettoa wooden frame member a hole is sunk in the latter to receive and closely fit the cup, and preferablya hole is drilled to receive the screw. e

The socket is then driven home by the application of a wrench or othensii ta le tool to the toolreceiving means providedat the stud-receiving end of the socket. In this ins ance the tool-receiving means is the octagonal peripheral edge of the flange 14 with which thetool may coo erate so that when the tool or wrench is turned the socket and screw will be rotated as a unit. In use the closure yields to the post when the latter isinserted and the post. is formed or provided with exbanding or laterally projecting engaging or hook members which engage the ca ch flange on the cup. When the post is unlatched the closure plate assists in expelling-it and closes the mouth of the cup. j j 1 That is claimed is:

' 1. A socket for curtain fasteners of the class describedcomprising a cup having an outer. flange at its mouth angular .in outline, an (annular member of similar'anoular periphery fitting over and embracing the flange and having aninwardly projecting lip, the cup being formed adjacent its bottom with a portion angular in transverse section, ascrew, the shankof whichp'rojects "axially through the bottomof the cup, the headof the screw being angular in outline to fit closely within theangular bottom portion of thecup, a plate her and a spring interposed between the plate and the bottomof the cup. 5 1 f 2.
